Hi Kelly,

use Regular Expressions <https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp>. This should be the easiest way to go:

---

var matching = "matching string 12345";
var not_matching = "not matching string 12a42";

// This checks if the last five characters are digits
var regex = /\d{5}$/;

alert( regex.test( matching ) );
alert( regex.test( not_matching ) );

Anybody can help me with such JavaScript code that can chop the ending portion of the string - last 5 characters - verifying if it is all numbers (zip code)?

Thanks.
